While the large-scale cosmological evolution is discussed in the upcoming §REF , it is worth to note here that at \(r\mathrel {{>\hfil #\hfil \crcr \crcr \sim \crcr }}100\)  kpc (and with Gyr frequency), the infalling sub-structures and interacting galaxies (in particular dry dark matter halos; see the HD simulation review by [1]}) can induce significant amount of sloshing in the IGrM, hence creating large-scale metal anisotropies and tails that are often correlated with cold fronts/contact discontinuities or ram-pressure stripping features [2]}, [3]}, [4]}, [5]}, [6]}, [7]}, [8]}, [9]}. For the observational insights on related metallicity maps we refer the interested reader to §REF .
